I've build myself a sign input on my website inside a modal popup. The problem is that I can have an unknown amount of modals generated in a foreach within PHP. Because of this my JavaScript code don't works anymore. Do you have any idea how I can improve my function to make it workable for a undefined amount of signature modals?
var signaturePad;
jQuery(document).ready(function () {
jQuery(document).on('opened', '#sign-modal', function () {
var signaturePadCanvas = document.querySelector('.signature-pad-canvas');
var parentWidth = jQuery(signaturePadCanvas).parent().outerWidth();
signaturePadCanvas.setAttribute("width", parentWidth);
signaturePad = new SignaturePad(signaturePadCanvas);
jQuery('#clear-signature').click(function () {
if (signaturePad) {
signaturePad.clear();
}
});
});
});

The reason why your modals have stopped working is because each modal you create is created with the same id.
This means that when you access the element with DOM, only the first element would be returned. Using a class is not the best idea as you lose the ability to target specific elements without looping.
The best solution in my opinion is to dynamically generate the id as you create your modals. This means you could have something like sign-modal-1, sign-modal-2 etc for each modal you create.
Then, in JQuery, you target elements with ID's that get opened, that begin with sign-modal, i.e. using the JQuery attribute selector.

I'm trying to add a class to a specific element that contains a parent container with a unique ID.
I have several buttons contained in a div, and all of them are using the same classes. For some reason, I can't use only $(this), so I created a loop that adds a unique ID to the containers.
HTML
<div class='section'>
<div class='btn-container' id='btn-1'>
<button class='btn'></button>
</div>
<div class='btn-container' id='btn-2'>
<button class='btn'></button>
</div>
<div class='btn-container' id='btn-3'>
<button class='btn'></button>
</div>
</div>
JQuery
$("button").click(function (e) {
e.preventDefault();
var target = $(e.target).parents(".button-container").attr("id");
console.log(target);
$(target).find(".btn").addClass("active");
});
I'm targeting the ID and it works, the console.log gives me back the correct info. However, for some reason, I can't add the class.
Thank you in advance for any help! (:
Edited:
I'm trying to add the class active to the button that is contained in the ID.
Example:
$("#btn-1 .btn").addClass("active"); but with the ID dynamically populate based on the info from the click.
Keep things simple, this should work
$(document).ready(function() {
$("button").click(function (e) {
e.preventDefault();
$(e.target).addClass("active")
});
});
.active{
border: 1px red solid;
}

<div class='section'>
<div class='btn-container' id='btn-1'>
<button class='btn'>Test</button>
</div>
<div class='btn-container' id='btn-2'>
<button class='btn'>Test</button>
</div>
<div class='btn-container' id='btn-3'>
<button class='btn'>Test</button>

Is there any code that I could add to the header of every page that would insert HTML at 2 or 3 points on a page (probably in the body), spread out evenly? This would be amazing for the platform that I am currently working on.
For example, maybe you wanted to embed a video using this. Ideally, I could put the code in the header, and it'd insert it 2 or 3 times in the body -- spread evenly.
Here you go: https://jsfiddle.net/westryder907/808xtyq7/
$(document).ready(function() {
$('.body > div').each(function(i, el) {
if (i % 3 === 0) {
$(this).append(" Inserted text via jQuery 2.2");
if (i > 3) {
return false;
}
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="header">
<div class="body">
<div class="region1">
Region1
</div>
<div class="region2">
Region2
</div>
<div class="region3">
Region3
</div>
<div class="region4">
Region4
</div>
<div class="region5">
Region5
</div>
<div class="region6">
Region6
</div>
<div class="region7">
Region7
</div>
<div class="region8">
Region8
</div>
<div class="region9">
Region9
</div>
<div class="region10">
Region10
</div>
</div>

Why not just edit your code and manually insert content from an external file with PHP?
I think more information is needed to fully understand why you'd want to approach this with your current method. It just doesn't make much sense to me why you would want to do it like this?
I have this HTML
<div id="main-container">
<div style="style-here" data-status="active" data-state="loaded">
<div style="style-here">
<div style="style-here" {{click_event}}></div>
</div>
</div>
<div style="style-here" data-status="active" data-state="unloaded">
<div style="style-here">
<div style="style-here" {{click_event}}></div>
</div>
</div>
<div style="style-here" data-status="inactive" data-state="unloaded">
<div style="style-here">
<div style="style-here" {{click_event}}></div>
</div>
</div>
</div>
On click on one of the elements that has {{click_event}} I want to search recursively till I can find an element that has data-status or data-state, and in the worst case when I meet the id from top to stop de search.
The HTML is made generated from another JS file and I can't change the way is made it. Is there a way with closest or parent from jQuery to search after data attribute?
Thank you.
No need for recursion, you can use closest():
$clickedElement.click(function() {
var $parent = $(this).closest('[data-status], [data-state], #main-container');
});
Is there a way to get a next element from a current sister element? Sorry if confusing.
<div class="wrapper">
<div class="paDiv">
<div class="saDivOne">
</div>
</div>
<div class="paDivTwo">
<div class="saDivTwo">
</div>
</div>
</div>
<script>
$('.paDiv').each(function(){
htmlContent = $(this).children().html();
SisterDivContent = $(this).next('.paDivTwo').children().html();
console.log(SisterDivContent);
})
</script>
$('.paDiv').each(function(){
var SisterDivContent = $(this).parent().find('.saDivTwo').html();
alert(SisterDivContent);
});
You have to add some contents inside div class 'saDivTwo'. Otherwise you will get empty content only.
Demo:
http://jsfiddle.net/U8n7g/
Try using .sibling:
$('.paDiv').sibling('paDivTwo').html()
I have the following structure of my HTML code:
<div id="bb-bookblock" class="bb-bookblock">
<div class="bb-item">
<div class="bb-custom-side">
Hello
</div>
<div class="bb-custom-side">
<button id="add">Click Here to add The page</button>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is first page</p>
</div>
<div class="bb-custom-side">
<p>Hello</p>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is second Page</p>
</div>
<div class="bb-custom-side">
<p>This is last page</p>
</div>
</div>
</div>
When I click on button with id=add I want to create the a new div after the last bb-item div with same two div inside it having class name bb-custom-side.
I know how to create the div using createElement and it a class, but I don't know how to create the sub div inside that newly created div. Can I associate with the last child or similar concept?
So after click event I want my HTML to be something like this:
<div id="bb-bookblock" class="bb-bookblock">
<div class="bb-item">
<div class="bb-custom-side">
Hello
</div>
<div class="bb-custom-side">
<button id="add">Click Here to add The page</button>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is first page</p>
</div>
<div class="bb-custom-side">
<p>Hello</p>
</div>
</div>
<div class="bb-item">
<div class="bb-custom-side">
<p>This is second Page</p>
</div>
<div class="bb-custom-side">
<p>This is last page</p>
</div>
</div>
<--Newly created div-->
<div class="bb-item">
<div class="bb-custom-side">
new div
</div>
<div class="bb-custom-side">
new div 2
</div>
</div>
</div>
Use clone() to create copy of div elements and append it to main div:
$("#add").click(function(){
var clonedDiv = $(".bb-item:last").clone();
clonedDiv = clonedDiv.find("div.bb-custom-side p").text("This is third Page");
$("#bb-bookblock").append(clonedDiv);
});
DEMO FIDDLE
NOTE: I just updated text for last div (This is third Page). You have to put it in loop to increase number.
Try this.
$('#add').on('click',function(){
$('.bb-item').eq(1).append($('.bb-item:last-child').html());
});
OR
$('#add').click(function(){
$('.bb-item').eq(1).append($('.bb-item:last-child').html());
});
Working Demo
You can try this.
$(document).ready(function () {
$("#add").click(function () {
$("#bb-bookblock").append('<div class="bb-item"><div class="bb-custom-side"> new div</div><div class="bb-custom-side">new div 2</div></div>');
});
});
DEMO
This may not appeal to everyone, but, personally, I tend to like "blank slates" for my cloning.
If it were me, I would do this:
var $baseItem = $("<div></div>").addClass("bb-item");
var $baseCustomSide = $("<div></div>").addClass("bb-custom-side");
$("#add").click(function(){
var $newItem = $baseItem.clone();
$newItem.append($baseCustomSide.clone().html("your_first_content_here"));
$newItem.append($baseCustomSide.clone().html("your_second_content_here"));
$("#bb-bookblock").append($newItem);
});
Unless there is a really good reason to reuse an existing element, I find you end up having to be a lot more complex to "scrub" the existing content from the clone . . . using a blank template always seems more clean to me.
